The inventors of the present invention have studied on the cutting of the thinned substrate by the base cutting process of the related art and found the following problems.
As shown in fig. 2, after the thinned substrate 11 is cut by the base cutting process, the vacuum automatic valve 22 is closed, the ventilation automatic valve 23 is opened, and the thinned substrate 11 is pulled upward by the loading part 13, the thinned substrate 11 is switched from the vacuum adsorption state to the air floatation state, and after the ventilation automatic valve 23 is opened, the gas flows along the gas path pipeline and the air holes of the base 21, and the specific flow direction is shown by the arrow direction in the figure.
As shown in fig. 2, the inventors of the present invention found that, at the moment of switching from the vacuum adsorption state to the air floating state, since the gas flow is not in a fixed direction, i.e., the friction force between the thinned substrate 11 and the base 21 is not in a fixed direction, the friction force has no significant effect when cutting the non-thinned substrate (the thickness of the box is generally greater than 0.8 millimeter (mm)), but when cutting the thinned substrate (the thickness of the box is less than 0.5mm), the friction force in the direction of no fixation causes the thinned substrate to shake, and further causes the thinned substrate to shift, as shown in fig. 3, the dashed line part in the figure represents the shift of the thinned substrate, and the thinned substrate cannot be precisely aligned before the next cutting.
The technical scheme of the embodiment of the invention is described below by combining the accompanying drawings.

Since the air outlet direction of the air tube 44 is adjustable in the embodiment of the present invention, that is, the inclined direction of the air tube 44 is not fixed, it is necessary to select a soft material for the airtight protection member 43 fixed between the porous wall of the base body 41 and the outer wall of the air tube 44.

Based on the same inventive concept, an embodiment of the present invention further provides a method for cutting a substrate using the transfer base, as shown in fig. 9, the method includes:
s901, controlling the substrate to be cut to be adsorbed on the base station body, and cutting the substrate to be cut for the first time;
s902, controlling an included angle between the air outlet direction of the air pipe and the plane of the base station body to be a preset angle, and controlling the substrate to be cut after the first cutting to be separated from the base station body.
Aiming at the step S901, controlling the substrate to be cut to be adsorbed on the base table body, and cutting the substrate to be cut for the first time:
preferably, before controlling the substrate to be cut to be adsorbed on the base body, the method further comprises: the extension direction of the control air pipe is vertical to the plane of the base station body; therefore, the inclination direction of the air pipe can be adjusted more conveniently subsequently.
The cutting method provided by the embodiment of the invention is described in detail below with reference to the accompanying drawings.
First, the thinned substrate 11 to be cut is moved to a predetermined position by the loading member 13, the thinned substrate 11 is large in size and generally needs to be cut into a plurality of medium-sized panels, and the arrow direction in the figure indicates the flow direction of the gas.
Next, the loading member 13 is lowered, the thinned substrate 11 covers the air holes 42 of the base body 41, and as shown in fig. 7, the linkage driving cylinder 53 is controlled to operate, so that the air pipe 44 is in a vertical state, that is, the extending direction of the air pipe is perpendicular to the plane of the base body; then, the automatic ventilation valve 23 is controlled to be closed, and the automatic vacuum valve 22 is controlled to be opened, so that the thinned substrate 11 is adsorbed on the base body, and the thinned substrate 11 is cut for the first time, and the specific process of the first cutting is similar to that of the prior art, and is not repeated here.
After the first cutting is completed, the thinned substrate 11 to be cut after the first cutting needs to be moved, so that the thinned substrate 11 after the first cutting needs to be further cut.
Specifically, the control linkage driving cylinder 53 sends an adjusting signal for controlling the linkage rod 51 to move, and the second connecting component 52 adjusts an included angle between the air outlet direction of the air pipe 44 and the plane of the base body 41 under the control of the adjusting signal, so that the included angle between the air outlet direction of the air pipe 44 and the plane of the base body is a preset angle, as shown in fig. 8, the preset angle can be set according to the thickness of the thinned substrate 11, and the thinner the thickness of the thinned substrate 11 is, the larger the downward deformation of the thinned substrate 11 is, so that the thinner the thickness of the thinned substrate 11 is, the larger the inclination angle of the air pipe 44 needs to be controlled.
As shown in fig. 8, the airtight protection member 43 has a corrugated shape, and when the inclination direction of the air tube 44 is adjusted, one side of the airtight protection member 43 is extended and the other side is compressed to ensure the airtightness of the air hole 42.
As shown in fig. 8, the automatic vent valve 23 is controlled to open, the automatic vacuum valve 22 is controlled to close, the loading member 13 sucks the thinned substrate 11 after the first cutting and lifts up for a certain distance (generally about 1 mm), so that the thinned substrate 11 after the first cutting is separated from the base body, and the loading member 13 sucks the thinned substrate 11 after the first cutting and moves to a predetermined next position, so as to perform the next cutting on the thinned substrate 11 after the first cutting.
In summary, the transfer base station provided in the embodiments of the present invention at least has the following advantages:
first, through the setting of airtight protection part, trachea and first connecting part, the gas flow direction is the same when realizing the air supporting state, when avoiding switching over from the vacuum adsorption state to the air supporting state, because the different thinization base plate that causes of frictional force direction takes place the problem of skew.
The second and the first connecting parts can adjust the air outlet direction of the air pipe so as to be suitable for thinned substrates with various thicknesses, and when the vacuum adsorption state is switched to the air floatation state, the problem that the thinned substrates with various thicknesses are deviated due to different directions of friction force is avoided, so that the thinned substrates with various thicknesses can be accurately aligned before next cutting.
Thirdly, because the gas flow direction is the same when in the air floatation state, the micro glass dust on the base station body can be blown away from the base station body when in the air floatation state, thereby playing a good self-cleaning role for the base station body and canceling the cleaning of a mechanical brush mechanism.
The foregoing is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
